Specification of Letters Patent.

. Patented July 3', 1917.

Application filed April 21, 1914. Serial No. 8,855.

To all whom it may concern:

Be it known that I, ROBERT E. HUGHEs, Jr., a citizen of the United States, residin at Nyack, in the county of Rocklandand Yorlg, have invented certain new and useful Improvements in Sewing- Machines, of which the following is a specification. This invention relates to sewing machines,

and more particularly to improved means for. makin -a triple seam, the object of the invention sing to provide means for trimfining simultaneously the edges of several pieces or plies of work and folding the' same, and then infolding such edges thereby to provide a triple seam made up of six plies of material, and to do this expeditiously aratively simple mechanism readily accessi'le'to the operator and one which is not liable to get out of order. In'working up material of various colors it is frequently very'diificult, if not at times impossible, to obtain a binding which will pro erlyor exactly match the color of the goo s, but by means of the resent improvement the necessity of binding the edge is entirely. avoided, while the cost" of productionis decreased.

I am aware that it is not new to'fold one edge of a iece of material for the purpose of sewing it to the raw edge of another piece thereof or even to fold both edges of such pieces or the purposeof sewing them to ther, but the present improvement has to o particularly with an improved mechanism Therefore it is the object ;of the present im rovement not only to provide mechanism which will produce a seam of the character described, but to provide means all cooperatingin such manner that the work to be'done theicby will be efficiently-performed, and

' ermore, to provide a mechanism in which all of the operatingparts will belocated in front of the needle and to also provide' amech'anismin which the several parts will cooperate with the presser foot, and in which also-the several parts will so cooperate that the necessity of feeding one layer or ply of material spaced 8, art from another la er or ply of material is avoided, so that t e several layers of material may be .l fed under thepresserffoot 'in the usual left to i of t e presser foot;

manner, that is one on to of and in engagement with another, wher'eliy the proper feeding of the several layers of material will simultan; ouslytake place.

In the drawings accompanying and forming part of this specification, Figure 1 is a front view of a portion of a sewing machine illustrating the present improvement appl'ed thereto Fig. 2 is a plan, partly section I, 'yview of-the present improvement; Fig. 8 isu'an endjview of so much of the machina :1 {is shown in Fig. 1, looking from k ghtpFig. 4 is a cross-sectional view taken;.'line 4-4, Fig. 1, and lookin towa'rd the left; Fig. 5 is a detail view 0% the throat the feeddogs; Fig. 7 is a perspective view of the infolder; Figs. 8 and 9 are detailwiews illustrating the operation .of such infolder plate; Fig. 6 is a detail view of' and thefiparts cooperating-therewith; Fi

of t e infolder; Fig.

In the present improvement' the several I plies of material, two or more, two being shown herein, are first fed under the presser foot, whereupon the edges thereof are trimmed and such-trimmed edges are then folded together-and the so folded edges then held and also to a. certain extent pushed in position for the action of the infolder, which then e gas the same and infolds the trimmede gosupon themselves, at the same time assisting'in feeding the folded Imaterial toward the needle, whereupon the needle penetrates the triple fold, thus proa 1e seam and making it unnecessary to bin bin Itwill of course be understood that this improved infolding means may be used with one layer of material or with two or more layers; as occasion may require. The present invention is in part an improvement upon: my prior Patent No. 1 075,422, dated October 14th 1913, and while in some respects the principle of operation of certain of the parts is similar the several'devices' operate in a somewhat different manner.

In-the resent improvement a somewhat different f drm of means for forming the first fold'is provided, in that in the present case a bracket is secured to the trimmer stand, having an upturned slightly curved guiding device for guiding the material to the trimmer','which in, the present in'stanoe likewise operates in a somewhat difl'erent manner from that shown in my prior case, in that the movable blade of the trimmeris horizontally supported for movement a horizontal path against the fixed blade of the trimmer, and carried by thistrimmer is a curved guard, which is eifective to deflect the trimmings out of the path of the needle;

at its lower end a detachable presser foot 9, which in the present instance is somewhat differently constructed from the ordina presser foot and the construction-of whi h is more clear] illustrated in Fig. 16. Located under t is r esser foot are the usual feed dogs 10 for t needle.

The forward or pro'ecting portion of the presser foot is upwar ly bent to form a recess, as 11, and in this recess'is located the fixed'blade 12 (see 2) and the movable horizontally working lade 13-of the trim: ming mechanism, the movable blade being reciprocated in a horizontal pathby suit- .able connecting means operated from the main driving shaft. ,v

The trimming bracket l4 is secured to. the base.2 as at 15. The bracket 14 has a vertical portion 16 terminating in an overhanging portion 17 provided with a bearing to receive one end of the vertical shaft 18, while the lower end of the shaft has a hearing in the portion 14 supporting the knife lever 19 for axial movement. A curved upwardly extending portion 20 of the lever 19 "eo'eives the movable knife 13 and operates.

. the seam is deter- 6 in guiding the work into the machine,

' former havin an upturned overhangportion 34 .which serves to fold over the material as shown in Fig. 14, so that the trimmed e e of the material is directed to the left of t e needle as distinguished from the practice heretofore of having the trimass to the right of the needle. A suitable ide iece 35 is so shaped and posi- I 'itione'd re tive' y to the knife 13 as to catch and deflect the trimmed portion out of the v faited .upon, the particular outline or shape not being essential so long as these devices a'ervelthe purpose of holding the code 'verti callyas it enters the trimmer an deflect the trimmed: margin away'from the needle.

--='1?he presser foot is recessed, as at 37, to

provide a working space for the gripper and t infolder to pass the material around the ;,;j f spring tongue 38, which is so shaped as to have ltsend extending in near the needle and bent downward to lie on the wall of the Presser-foot, as at 39, so as to hold the seam after it has been formed. The needle erates in a cut-out at 40, while the top fee ing memberoperates behind the needle close to .gsithe wall 41 ofthe presscr foot. The feed 1 dog is [to the trimmer at the front and provided;

Hrovided with a suitable toothed surface an is so shaped as to operate close with an upwardly extending heel 42; which prevents the seam from moving laterally I ,awa from the needle-line as the .the material er and info der are-acting upon the wor l he cut- 1 .out43. is for the passage of the looper formingwpart of the stitch mechanism. A detailed description of this, however, is deemed unnecessar as it forms no part of this invention. t is obvious that this im roved folding'and trimming mechanism to orm. a tri le seam may be applied to any-of the we 1 known stitchin machines. i ,The feeding mec anism is of the" well known four-motion variety. The feed dog 10 operates through the 'slots 44 of the throat plate 45, see Fig. 5. v A guard 46-is secured to the end of the plate to direct the seam of assing through the machine from the moving parts so that it willbe delivered in clean condition. The needle reciprocates through the usual needle hole 47 in the formation of the stitch. Secured to thegresser foot bar 8, as at 48, ishne end of racket 49, which operates in, a slot 50 of the machine head 5 and is guided therein for vertical movement with the presser foot and bar. ,At 51, see Fi s. 4 and 17, is secured thev "mechanism of t e infolding'and clamping members. A bracket 52is provided with a bearing 58 for the shaft 54, the other end being provided with a. .bearin '55 for the shaft 54 adjacent the needle. his bearing extends downwardly, terminating in another bearing 56 for the rock shaft 57, which carries the gripper 58, the other end of the shaft 57 bein provided with a collar 59.

From the ore oin both shafts 54 an 57 ave the same vertical movements as the presser foot orpresser bar,- being connected therewith. The shaft 54 is reduced, as at 60, affording a shoulder 61 for the block 62. A sleeve 63 afi'ords another shoulder for the block 62, while the nut and lock-nut 64 isprovided for ad'ustin these p artsso that the shaft 54 will ave rec rotary movement in the block 62 and be reciprocated in the directionof its length to the same extent as the feed dog 10, by-means ofa link 65 connected to theblock 62 at one end and to a bracket 66 secured to the feed bar 67. The gripper 58 is as hereinbefore stated, formed with two arms, and is conit will be seen that nected as at 68, with the rod 69 for movement therewith. The rod 69 is provided with an adjustin means 70 to regulate its length, and terminates in a telescopic con-' nection, as 71' (see Fig.2), having a compression spring located therein to cushion the gripping action on the material and compensate for variation in thicknesses. This connection 71 is bifurcated, as at 72, to

receive one end of' a bell crank lever 73.

pivoted as at 74 in""a bracket 75, the other arm 76 of the lever being connected to a link 77 which is actuated by the 'oint 78 pivotally secured as at 79 to the nee le lever 6 (see Fig. 1). A ball and socket 80 is also secured to the needle lever, and a reciproeating rod 81 having a ball and socket 82 connected to the arm 83 of the infolder 84 is secured to the shaft 54. The 'work-engaging end 85 of the infolder is so shaped as to operate within the recess 37 "and'pass underneath the end of the spring tongue 38 .to project the cut edge of the material to the right of the needle, and to turn the edge of the material around the portion 39 of the ton e. The ppm: 58 also works in the sai v recess and h y reason of'itsrecessed portion 86 acts to further fold the edge into an overlappin position on the material, that suc Ifolded edge for the action of t e in folder, while its heel 88 prevents the material from bulging or moving laterally.

is attached to the feedldog 1O ins'uch a manner as to control the size and width of the seam. Secured to the presser bar, as at 89, see Fig. 3, is a yoke 90, which clamps a it a ha f fold and then properl. hold the guide bar 91 so that it has thesame vertical movement as the resser bar 8, and. secured to the end of this ar 91is a bracket 92 whichfextends upward and outward and ,is so shaped as to straddle the presser .barlso 12 0 This heel coiiperates with the heel 42, which f' seam,

Fromthe foregoing it "will be obvious that, n addition to the movements rovided for folding the material to form t bending it over, It, outwa third, turning it under, I have so organized-they several parts that certain of them, including the gripgier, 'infolder, top feed, act upon. he seam o foot 9 and acts upon a portion of the ma w ich was caused by the' viated by theuse of this improved mecha--- triple second, turning the material, I to move in unison with the feed dog to.

seam is obtained by amore gradual folding of the edge of the material, one advantage of which permits the use of the horizontal knife hereinbeforereferred to and the trim- .ming of-the'material after the first fold.
